Abstract	Discrete wavelet transform (DWT) and embedded block coder (BC) are two main modules in JPEG2000 compression system. Data transfer between the DWT and BC modules presents challenges due to difference in data format generated by the DWT and data format required by the BC module. In this paper, we investigate data transfer and storage techniques between the DWT and BC modules. We propose an efficient memory organization and data transfer schemes to reduce the data bandwidth. A VLSI architecture for the proposed data transfer system is proposed and synthesized for TSMC 0.18- process. Simulation results show that our proposed techniques result in approximately four times less bandwidth for the BC module while requiring an extra hardware cost of only 11%.
